Purpose of the study: This study aims to analyze rosella flower extract supplementation on blood glucose levels after physical activity. Methods: This experimental research uses a pre and post control group design. Subjects were selected using purposive sampling technique. A total of 20 healthy men aged 19-25 years participated in this study and were divided into two groups, namely group K1 with placebo and K2 with rosella flower extract at a dose of 500 mg. Data collection begins with collecting data on subject characteristics. Next, the subjects were asked to warm up and do physical activity in the form of running 2400 meters with moderate intensity. One hour after running 2400 meters, the subject took a pre-test blood draw to measure blood glucose levels. Then the samples were given supplementation intervention based on their respective groups, K1 by giving a placebo and K2 by giving rosella flower extract at a dose of 500 mg. 60 minutes after administering the supplementation intervention, the subject underwent a post-test blood draw. Results: The results of this study showed that there was no decrease in blood sugar levels in either the control or treatment groups (p > 0.05). Conclusion: It can be concluded that administering rosella flower extract after physical exercise does not have a significant effect on reducing post-exercise blood glucose levels. © 2025 National Electronic-Information Consortium (NEICON).
